Recent change in training suggestions

Recently I've started encountering an issue where I will complete a very specific running workout, and then only once I complete that workout my watch will immediately suggest the exact same thing for a few days later. 

This is inconsistent both with how my watch used to behave and basic training plan principles. 

For instance, last night I had a suggestion for a 35 min threshold run with 15 minutes at threshold pace. I saw that 2 days later the Daily Suggestions listed an interval workout. However, as soon as I completed the threshold workout I checked my watch again and 2 days later it listed the same 35 minute threshold run. 

I've noticed this happen multiple times recently and it never used to. To me it seems like a bug. 

Has anyone else encountered this issue?
